Not sure if you read my review (I'm the one who started the thread lol), I was going to do like you want to do to the stock. The plastic stock was so warped it wouldn't have worked unless I cut almost all of one side of the barrel channel off.
"I decided to try to free-float the barrel tonight. I took my Dremel tool and smoothed out the pressure point in the front of the stock that the barrel rests on. It looked perfect, until I re-installed the barrel and action into the stock. The stock must have been warped and it was applying major pressure on the left side of the barrel, because when I re-installed the "free-floated" stock, the stock contacts the whole left side of the barrel. So much for a free-floated barrel..."
I bought a Bell and Carlson stock. Here's a pic now lol.
